FanPicksFromData

public FanPicksFromData()

Create a fan maker that will use two nearest raw data points(closest in range, beam measurements either side of the fan image point).

FanPicksFromData

public FanPicksFromData(int nNearPoints)

Create a Fan maker.
Valid values are
1. Use a single nearest point from the raw data
2. Use the nearest points in range, and a beam point either side of the output point
4. Weighted average of four nearest neighbours.

Parameters:

nNearPoints - . The number of raw data points to use for each point in the fan.
